443.75 - (25 x 7.25) =25x
443.75 - 181.25 = 25x
262.5 = 25x
x = 10.5
$10.50
The account A has amount $600 and B has $1600.
<u>Step-by-step explanation:</u>
The given equations are:
a+b=2200 ⇒1
0.03a+0.05b=98 or +⇒2
Change the first equation by isolating a,
a = 2200-b. ⇒3
Apply equation 3 in 2,
+=98.
66- +=98.
66+ = 98.
6600+2b=9800.
2b=9800-6600.
2b=3200.
b=1600.
Substitute b value in equation 3
a=2200-1600.
a=600.
or:
or:
x₁=3, x₂=4, x₃=5, .... x₈=10
Answer:
288
Step-by-step explanation:
288+248=536
Part A: <u>(8 × (-4))</u> <u>(-6 × (-4))</u> <u>(3 × (-4))</u>
Part B: -6 × -4 = 24. So when multiplying -6 by -4, the product should be <u>24</u>
But basically, Tiana's way of solving this question is correct while Amit's is incorrect.And this is because Amit is using PEMDAS, unlike Tiana.
